Abstract

The gender wage gap expanded from 1940 and 1975 but narrowed sharply from 1980 to 1995. We use the model introduced in Ben-Porath (1967) to assess the role of gender differences in life cycle profiles of market time in explaining the gender wage gap dynamics over the long run. Men’s profiles changed little across cohorts, but women’s profiles converged to those of men, and especially so in higher-paying occupations. We calibrate the model and find that the implied trends in unobserved investment in human capital accumulation account for most of the long run gender wage gap dynamics. The most notable effect of changing market hours was to reduce investment incentives for men in lower-paying occupations and to increase them for women in higher-paying occupations. The roles of changing occupation-specific skill prices and cohort-specific endowments are less pronounced.
